The omapdrm and omapdss drivers are architectured based on display
pipelines made of multiple components handled from sink (display) to
source (DSS output). This is incompatible with the DRM bridge and panel
APIs that handle components from source to sink.
Reconcile the omapdrm and omapdss drivers with the DRM bridge and panel
model by reversing the direction of the DSS device .enable() and
.disable() operations. This completes the move to the DRM bridge model,
with the notable exception of the DSI pipelines that will require more
work.
